' To all whom 'it may concern:

Be it known that 'I, J osar KLOIBER, a subject of the German Emperor, residing at.

Oregon City, in the county of Clockamas 5 and State of Ore on, have invented certain,

of making patterns for producing on paper water marks of various designs.

water marks on paper consists in that wires are pressed on the moist pu1p.- To produce complicated designs by such process is evidently very diflicult and expensive.

Theobject of my invention is to enable the production of any desired water mark design on paper. To accomplish this, I form paper patterns, by first making paper boards, then etching the desired design in lates of anysuitable ri 'd material, ascopper, zinc or the like, t enmaking an impression of the etched design on. a sheet of paper containing a layer of a certain chemical composition and bysubsequently pasting the said sheet'on the paper boards. The paper patterns are then applied in calender machines in lieu of the wires, to make the impression in the paper. The paper patterns can be repeatedly used and when worn out can be turned into paper pulp. The paper boards are made as follows: I prepare a mixture of potato starch, dissolved casein, paper pulp, ammonia and water, which mixture is boiled and then cast into the shape of boards or plates. I then have plates of suitable r' id material, as copper, zinc or the like etc ed in accordance with the desired design. I then prepare a paste like mixture of water, gelatin, lime, sal- 'miac,' alcohol and glycerin, which mixture I i boil and filter. I then apply a layer lot this p ace on paste on a sheet of paper, which This sheet-having the embosse then allowed to cool off and is pasted to the The hitherto used process of producing" mass on to sea top of the etched plates. Under the application of heat'I roll this paste-likemasson top of the etched plates so that the design is lmpressed thereinand in the paper sheet.

design is above named paper board, which now forms the pattern. The pattern boards may be used in calender machines in the same manner as the hitherto used wires for the pro duction'of "water marks in paper..

What-I claim and desire to secure by LettersPatent-is:

1. A'method of making patterns for the productionon paper sheets of water marks of various desi s, consisting in first making pa er boar s or plates, thenetching the desire design in rigld plates,.then placing the sheet of paper on top of the etched design, then applying a layer of paste-like paper, thereupon making an impression of the said etched design in said layer and finally pasting the said embossed paper sheet onto the plate.

2. A method of making patterns for the production on paper sheets of water marks of various designs, consisting in first making pa er boards or plates, then etching the desire design in rigid plates, then placing a sheet of paper on top of the etched design,

said paper board or 'then applying a layer of a paste-like mass prepared of water, gelatin, lime, salmiac, alcohol and glycerin on top of said paper sheet, rolling over said layer under application of heat, and thereby making an impression' of the design therein, and in the paper, cooling said sheet and pasting thesame onto the paper board or plate.

In testimony whereof I afiix my signature in presenceof two witnesses.
